An autofocus (AF) frame integration unit generates at least two groups, each group including at least one focus detection area based on a comparison between a plurality of focus detection results, the plurality of focus detection results to be obtained corresponding to a specific time. A movement determination unit determines whether an object corresponding to a first group and a second group is moving, based on a focus detection result corresponding to the first group, generated based on a focus detection result corresponding to a first time, and a focus detection result corresponding to the second group, generated based on a focus detection result corresponding to a second time later than the first time.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image processing apparatus according to claim 1, wherein in a case where a difference between a representative value for the focus detection result in the second group and a representative value for the focus detection result corresponding to the second time in a third group is more than the first threshold and less than a second threshold, the grouping unit groups the third group into the second group.
3. The image processing apparatus according to claim 2, wherein in a case where the difference between the representative value for the focus detection result in the second group and the representative value for the focus detection result corresponding to the second time in the third group is more than or equal to the second threshold, the grouping unit does not group the third group into the second group.
4. The image processing apparatus according to claim 1, wherein in a case where the number of focus detection areas included in a group generated by the grouping unit is less than a threshold, the determination unit does not use the group for determination.
13. The control method according to claim 12, further comprising grouping the second focus detection area into the second group, in in a case where a difference between a focus detection result corresponding to a first focus detection area included in the second group and the focus detection result corresponding to the second time in a second focus detection area adjacent to the first focus detection area is less than a first threshold.
18. The image processing apparatus according to claim 17, wherein in a case where a difference between a focus detection result corresponding to a first focus detection area included in the second group and the focus detection result corresponding to the second time in a second focus detection area adjacent to the first focus detection area is less than a first threshold, the grouping unit groups the second focus detection area into the second group.
19. The image processing apparatus according to claim 18, wherein in a case where the difference between the focus detection result corresponding to the first focus detection area and the focus detection result corresponding to the second time in the second focus detection area is more than or equal to the first threshold, the grouping unit does not group the second focus detection area into the second group.
20. The image processing apparatus according to claim 18, wherein in a case where a difference between a representative value for the focus detection result in the second group and a representative value for the focus detection result corresponding to the second time in a third group is more than the first threshold and less than a second threshold, the grouping unit groups the third group into the second group.
21. The image processing apparatus according to claim 20, wherein in a case where the difference between the representative value for the focus detection result in the second group and the representative value for the focus detection result corresponding to the second time in the third group is more than or equal to the second threshold, the grouping unit does not group the third group into the second group.
